PCA9534

8-bit I²C-bus and SMBus low power I/O port with interrupt

Rev. 4 — 7 November 2017

Product data sheet

1. General description

The PCA9534 is a 16-pin CMOS device that provide 8 bits of General Purpose parallel

Input/Output (GPIO) expansion for I²C-bus/SMBus applications and was developed to

enhance the NXP Semiconductors family of I²C-bus I/O expanders. The improvements

include higher drive capability, 5 V I/O tolerance, lower supply current, individual I/O

configuration, 400 kHz clock frequency, and smaller packaging. I/O expanders provide a

simple solution when additional I/O is needed for ACPI power switches, sensors,

push buttons, LEDs, fans, etc.

The PCA9534 consists of an 8-bit Configuration register (Input or Output selection); 8-bit

Input register, 8-bit Output register and an 8-bit Polarity Inversion register (active HIGH or

active LOW operation). The system master can enable the I/Os as either inputs or outputs

by writing to the I/O configuration bits. The data for each input or output is kept in the

corresponding Input or Output register. The polarity of the Input Port register can be

inverted with the Polarity Inversion register. All registers can be read by the system

master. Although pin-to-pin and I²C-bus address compatible with the PCF8574 series,

software changes are required due to the enhancements and are discussed in Application

Note AN469.

The PCA9534 is identical to the PCA9554 except for the removal of the internal I/O

pull-up resistor which greatly reduces power consumption when the I/Os are held LOW.

The PCA9534 open-drain interrupt output is activated when any input state differs from its

corresponding input port register state and is used to indicate to the system master that

an input state has changed. The power-on reset sets the registers to their default values

and initializes the device state machine.

Three hardware pins (A0, A1, A2) vary the fixed I²C-bus address and allow up to eight

devices to share the same I²C-bus/SMBus.
